To address the economic feasibility of auto-guidance and lightbar global positioning system (GPS) navigation technologies, a linear programming model was formulated using data from U.S. Corn Belt farms. Five scenarios were compared: (i) a baseline scenario with foam, disk or other visual marker reference, (ii) lightbar navigation with basic GPS availability (+/-300 mm accuracy), (iii) lightbar with satellite subscription correction GPS (+/-100 mm), (iv) auto-guidance with satellite subscription (+/-100 mm), and (v) auto-guidance with a base station real time kinematic (RTK) GPS (+/-1 cm). Results indicate that auto-guidance is profitable only when farm size can be increased.
